To all whom it may concern:

Be it known that I, WILLIAM M. RAPP, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in-- plication filed August 17, 1910, for linotype machines, and given Serial No. 577,640.

The invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1, is a view in front elevation illustrating the assembling mechanism of an ordinary linotype machine with my improvements in po-. sition. Fig. 2, is a top plan view of the mechanism shown in full lines in Fig. 1. Fig. is an end view, and Figs. 4, 5, and 6, are views of various details of construction.

Referring particularly to Fig. 1, a portion of the frame 1, the elevator 2, and the star wheel 3 of an ordinary linotype machine are illustrated in dotted lines, and my improvements illustrated in full lines in their cooperative relation to the parts above referred to. 4, is the assembler slide which is made-in sections providing longitudinal slots 5 through which a guide block 6 projects to guide the sliding movement of the assembler slide, and 7 is a spring bar for drawing the slide longitudinally to its starting point with its adjust-able finger 8 against star wheel 3. This assembler slide is moved in the opposite direction as the matrices 9 and spacebands 10 are assembled and moved into position between the star wheel and finger 8. A toothed rack 11 is formed on the upper edge of the slide 4,

spaced, from the gear by means of a block or sleeve 16, and this dial is provided with i a scaleiaround its periphery, beginning with" zero and numbered up to twenty-nine, d1- viding the dial into thirty marks indicating pleas.

To brake the assembler slide, I employ a brake lever 33 which, is pivotally supported between its ends on a screw. pivot 34.: One end of this lever 33 is bent upwardly and laterally as illustrated in Fig. 5, and ro- 'jects into a bifurcated bracket 35, w ich may be of rawhide or other suitable: material if desired, the two members of this bracket 35 having recesses 36 to receive, the lower longitudinal member of the assembler slide to straddle the same. The opposite walls of these recesses 36 are beveled as shown, so that when the bracket is in asents a wider surface to the slide and alto tilt bracket 35 slightly, the latter prelows it'to move rearwardly. The long end of this lever 33 is made witha bifurcated bracket 37,and a lever 38 is fulcrumed between its ends on the screw pivot 34, and at one end is located in the bifurcated bracket 37 The opposite end of this lever 38 is located in the path of movement of the elevator 2, so that when the elevator moves upwardly to carry the assembled line' of mat-' rices, it will engage this lever 38, and the latter will move the bracket lever 33 so as to release the assembler slide and allow itto be drawn backward by means of the spring bar 7. This brake 33 may also be operated by hand or foot power-whenever desired, and is held in normal position by a spring 45.

Various slight changes might be made in the general form and arrangement of parts I chine and an assembler slide, a brake lever where they engage the slide, one end of said I I 1 pivoted between its. ends, a bifurcated bracket having notches receiving the slide,

lever projecting into said bracket and constrncted to tilt the same when the lever is moved, the other end of said lever bifur-- cated, and a brake operating'lever located in the bifurcated end of said brake lever, substantially as described.

In testimony whereof I have signed m 20 name to this specification in the two subscribing witnesses.
